  • Patent number: 6510941
    Abstract: An endless conveyor belt has a thermal fluid (gas or liquid) sprayed against a portion of its underside to define a temperature-controlled region of the belt. To prevent the lateral escape of the thermal fluid, stationary seals are provided which contact the belt underside adjacent respective longitudinal edges of the belt. To keep the seals in continuous contact with the belt, despite warping that might occur, the seals carry magnets, and the belt is formed of a magnetizable material. Hence, the magnets force the belt and seals together.

  • Patent number: 5775380
    Abstract: After a warp beam on a loom is used up, its old warp threads are separated from a material being woven on the loom. The used-up beam, together with its residual old warp threads, is then mounted on a transport device and moved away from the loom. A winding element rotatably mounted on a maintenance device is positioned adjacent the transport device. Leading ends of the old threads are affixed to the winding element and separated from the used-up beam, whereafter the used-up beam is replaced by a new beam. Leading ends of new threads on the new beam are attached to trailing ends of respective ones of the old threads, whereafter the winding element is rotated to wind-up the old threads and parts of the new threads, while pulling the new threads through a loom device (such as a warp stop motion device, and/or a shedding device, and/or a weaving reed) carried on the transport device. Then, the winding element is rolled along a guide surface to a removal device.

  • Patent number: 5770235
    Abstract: A hollow drum is rotatable about a horizontal axis and includes openings around its circumference for discharging drops of a free-flowing substance onto a cooling belt in the manufacture of pastilles. A stationary body disposed inside the drum is spaced from the interior surface of a front side of the drum to form therewith a sickle-shaped gap leading to the drop-forming zone. A channeling member rests against an external surface of the front side of the drum to form therewith an upwardly open channel. The supply passage which delivers the freely flowable substance to the drum can be defined by the channel, whereby the substance would be fed into the upwardly open end thereof and would flow into the gap through the drum openings. Alternatively, the supply passage could be defined by a space within the stationary body which communicates with the gap at a location disposed above the drop-forming zone.

  • Patent number: 5720985
    Abstract: In order to form separate particles from a flowable mass, the flowable mass is fed through a pipe and extruded through holes formed along a longitudinal axis thereof. The pipe is oscillated by an agitator in a direction transversely of the longitudinal axis to cause the extruded mass to be sheared-off in the form of particles. Stop members can be positioned adjacent respective sides of the pipes to be contacted by the pipe and thereby define change-of-direction points for the pipe during its oscillation. The agitator may include piezoelectric ceramics attached to the stop members.
